Variables were subjected to a post-hoc verification process. 1 represents detailed post-hoc verification of variables using automated screening for plausible ranges of values and random manual checks. 2 represents moderate level of scrutiny ensuring variables are within a plausible range. 3 indicates lack of post-hoc verification process. 4 indicates the variable was derived from external sources based on GPS surveyed field location coordinates: administrative units were derived from shapefiles provided by the Geo-Information Services Division, Uganda Bureau of Statistics. Altitude (masl) was derived from the SRTM 90 meters digital elevation model (DEM) version 4.
